METHOD OF COVERING EYELETS- WITH A FLExIBLE MATERIAL.

To all whomit may concern:

Be it known that I, PERLEY R. GLASS, a citizen of the United States, residing in Boston, county of Suffolk, Commonwealth of 'Massachusetts, have invented certain new and useful Improvements 1n a Method for Covering Eyelets with a Flexible Material, of which-the following is a specification, reference being had to the drawings accompa nying the same.

My invention relates to a method for covering eyelets with a flexible material, such as celluloid or rubber or a like material.

The objects of my invention are as follows:

to provide a method for covering eyelets with a material cut or formed of the proper size and thickness to form the covering for an eyelet;

My invention comprehends the covering of eyeletswith ,celluloid or rubber when in a hardened or flexible condition by forming or sha ing the material to the proper shape and thic ness and thereafter pressing it upon the head of an eyelet with a former shaped to v cover said head with a uniform thickness and to form it around the head by a rubbing. frictional contact with the material and to produce sufiicient friction with the material to develop a frictional heat that will soften and prevent the material from cracking, so

as to assist in shaping it to the form of the head of the eyelet.

In the drawings accompanying this specification, Figure 1 is a sectional elevation of an eyelet-covering apparatus, showing the eyelet and the materia in posltion ready to be formed around the head of the eyelet. Fig. 2 is a sectional elevation same as Fig. 1., showing the dies partially closed and the material artially bent or formed around the head of t e eyelet. Fig. 3 is a partial sectional elevation of the forming-dies, taken at right angles to the elevation shownin Fig. 1

and shows the completion of the process of forming the materia around the head of the eyelet and the eyelet in crosssection as com pleted. 1

In the drawings, 1 represents the upperdie holder, and 2 the lower-die holder.

3 3 re resent the rods connecting the upper and ower die holders, which rods have or their purpose to keep the die-holders in proper ahnement and to limit their movement away from each other.

rods 3 3, serv ng Patented April 9, '190 7.

4 4 represent spiral springs surrounding the rods 3 3 and pressing against the upper and lower die holders 1 and 2 and serve to press. them apart.

5 represents the lower-die-holding block, in which there is a bearing in which the lower forming-die 6 is free to move vertically.

7 is a spiral spring pressing upwardly against the bottom of the lower forming-die 6, its lower end pressing against the adjustingscrew 8. The adjusting screw 8 is threaded into the bottom of the die-holder 5.

9 is an upwardly-projectihg point in the forming-die 6, adapted to receive and center the material and the eyelet.

10 is a c'oncaveannular groove in the top of the formin die 6, formed in the shape of a covered eye et.

11 is a pressingedie which has a sliding bearin in the up er forming-die 15. It is presse downward y bythe spiral spring 12, which contacts with its top portion. The spiral spring 12 has abearing at its upper end against the adjusting screw 13,-which is screw-threaded into the top of the die-holder 1. The recess 14 is arranged to receive the projectin point 9. The part 15 is threaded into the ie-holder 1. 16 represents an eyeet, 11, which is adapted to press against the top of the eyelet 16 to move it downwardl to form the material 18 around the head 0 the eyelet in the annular forming portion 10 of t e die 6.

19 19 represent the upper forming-die, and 20 20 represent the concave lower end of said upper forming-die. is adapted to press against the upper edge of the covering materia 18 and turn it inwardly and form it around the edge of the head of the eyelet, as shown in Fig. 3.

21 is a stop on the adjusting-screw 8 ,which is adapted to contact with the bottom of the lower forming-die 6.and limit its downward movement. 5

22 22 represent heads on the lower ends of the rods 3 3 to limit the movement of the holding-dies 1 and 2 away from each other, and 2323 are nuts on the upper end of said the same purpose as the heads 22 22--t. 6., to limit the movement of the holding-dies 1 and 2 away from each other.

The method of covering an eyelet by the apand 17 the lower end of the presser-die' The forming-die 19 19 paratus shown herein is as follows: The holding-dies 1 and 2 are moved a sufficient distance terial away from each other to allow the placing of the material 18 andthe eyelet 16 upon the end of the centering-point 9. "Thereafter the presser-die 11 is moved downv ardly by any suitable means as a power-press, to press the eyelet 16 downwardly against thematerial 18, thereby pressing it into the concave forming portion '10 of the lower die 6 to bend it, as shown in Fig. 2. This pressure continues until the forming-die 6 contacts with the stop 21. Thereafter the spring 12 will be compressed, the upper forming-dies 19' 19 continuing downward until the concave edges 20 20 contact with the upper edge of the ma- The upper formingdies 19 19 are mounted on the portion 15 in such manner as to revolve freely thereon and are held in their adjusted position by means of the pin 25, projecting into the groove 26. The formingdies 19 19 have gear-teeth 24 on their upper edge adapted, to enmesh with the revolving gear 27; which is revolved in any suitable manner through the medium of the shaft 28.

l wardly aroun saaeoe Thefrictional revolving contact of the u per forming-grooves 20 20 against the edge 0 the material will the outer edge of the eyelet 16 until it'is' in the form shown'in Fig. 3.

What I claim is A method of covering eyelets consisting in forming the covering material of the proper shape and thickness; to cover an eyelet; of placing the eyelet and material in a holding and centering device; of pressing the eyelet upon the material into a lower forming-die to partially form the material around thehead of an eyelet; and thereafter pressing an upper formin -die upon the partially-formed material an rotating saiddie upon the material to com lete the shapin of the material to covert e head of an eye et.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing 45 witnesses this the 27th day of May, 1905. PERLEY R. GLASS. Witnesses:
